Abstract
Short glass fiber reinforced (SGFR) PA6,6/PP blends with 20 wt% styrene-ethylene/butylene-styrene triblock copolymers (SEBS) grafted with different levels of maleic anhydride (MA) were studied using both the essential work of fracture (EWF) and J-integral fracture toughness techniques. Good linearity was found between the plane strain specific fracture work, wf, and the ligament length, l, in single-edge notched bend (SENB) specimens. The two fracture mechanics parameters were compared and there was good agreement between the J-integral fracture initiation toughness, JIC, and the specific essential fracture work, wIe. The skin-core morphology characteristic of injection molded short fiber reinforced thermoplastics (SFRT) was also revealed using the EWF approach.
